How to do a simulation of still water being affected instead of flowing water
You can use an Object set to a Flow Behavior of Geometry to convert any part of the mesh that intersects with your domain to liquid particles.  You'd just have to allow a limited amount of time to settle and keyframe the visibility of the object.


Particle sims, and particularly this process, seem pretty finicky right now.  I had to go back and change the number of divisions on my domain to sort of &quot;refresh&quot; the sim and update the size and positions of my emitters.  Just a heads up.
